What are the hidden dangers of supermarket shopping?
Hidden danger one
Shopping baskets are seriously polluted.
Shopping carts and shopping baskets in supermarkets are frequently reused, and the cross storage of raw and cooked foods is quite serious. If you look closely at the supermarket, many of these shopping tools can see stains and rust.
Relevant studies have confirmed that there are about 1 100 colonies on the surface of shopping cart handrails alone, far exceeding the colony number of public toilet doorknobs and computer mice in Internet cafes, but China has not yet issued relevant national hygiene standards. How long it takes to clean or disinfect shopping carts and shopping baskets in supermarkets depends entirely on consciousness. So it left a great health hazard.
Tips: When shopping in the supermarket, cooked food should not be directly thrown into the shopping cart or shopping basket, but should be isolated on the outer packaging before being put in; After using shopping tools, you should wash your hands and disinfect them immediately after returning home, especially children are more likely to be infected with germs in shopping carts. Don't let children eat their hands, wash their hands and change clothes in time.
Hidden danger 2
Set off freshness with lights
Although the supermarket itself is well lit, there are many lights hanging above the fresh food counter, and the lampshades in different sales areas are different in color. There are red lampshades in the raw meat area, green lampshades in the vegetable area, orange lampshades in the fruit area and yellow lampshades in the bread counter. It is the colored lights produced by different lampshades that cover up the defects of food itself, make all kinds of fresh food look unusually fresh and moving, and arouse consumers' desire to buy.
Tips: Everyone should pay more attention when shopping, try not to be disturbed by lights, and look and smell more to distinguish the quality of food, so as not to buy rotten food and damage your health.
Hidden danger three
Shelf life of homemade food
Compared with some bazaars, consumers feel that homemade food in supermarkets is more hygienic and safer. Although the food hygiene in most supermarkets is generally good, there are still quite a few homemade foods with different degrees of hygiene problems, especially the shelf life of food.
Replace the production date with the packaging date, or change the date, etc. Deceiving consumers is a common interference method in some supermarkets. Supermarket staff usually put the date on the plastic bag after weighing. Although this date shows the date of the day, consumers have no idea when these foods were produced. What's more, some producers and operators unscrupulously use food labels to change the date, or re-package, and arbitrarily extend the shelf life.
Tips: Try to choose fresh products that have just come out of the pot, and eat less cold salads that are perishable; When buying, carefully check the production date, shelf life and other signs, and pay attention to whether the packaging is intact. Don't buy those with incomplete labels and damaged packaging; Beware of home-made food discount promotions. Most of these activities are aimed at foods that are about to expire, and the safety index is not high. Don't buy in large quantities for the sake of cheapness.
Hidden danger four
It's unsanitary to try it.
Supermarkets often put sausages, meatballs or drinks in front of the counter for customers to taste for free, which is actually very unsanitary. You see, some salespeople are foaming at the mouth when processing food. Tasting products are placed in the open air for a long time and exposed to the air without any dust-proof measures. They are randomly placed in lunch boxes and paper cups for customers to eat. There are also customers who directly pinch it with their hands and taste it, or pick it up and smell it before putting it back, and the food is polluted.
Tips: before you try, you should pay attention to whether the promoters who process food are standardized. If they don't wear masks and gloves to work, or don't take necessary dust-proof measures such as transparent glass plate isolation for tried food, they should refuse to eat it; Pay attention to the outer packaging of the sample itself, and see clearly the production date and shelf life before eating; Use disposable toothpicks or paper cups when eating to avoid endangering the health of others.
Hidden danger five
The environment is closed and uncomfortable.
Closed supermarkets are short of fresh air, usually with a large flow of people and heavy air pollution. If you stay too long, it is easy to cause headaches, dizziness, chest tightness, nausea and other discomfort.
Tips: It is best not to spend more than 2 hours shopping in the supermarket. Old people, children, pregnant women and people with basic diseases should pay special attention to controlling the stay time and leave in time if they feel uncomfortable.
Supermarket shopping tips
Try to go shopping in the supermarket or take a free shuttle bus, which is convenient and can save the transportation fee to the supermarket. Shopping on the way home from work can save time. Many communities have free shopping buses. Shopping by free bus can not only go back and forth directly from the community to the supermarket, but also cost nothing. At the same time, don't worry, you can take things home with confidence after buying.
When shopping, try to bring reusable shopping bags. Since the country adopted the policy of banning plastic bags, supermarkets no longer provide small plastic bags for shopping free of charge. Instead, they use environmentally-friendly degradable plastic bags for a fee, and each bag charges. If you want to buy a bag every time you shop, you have to spend a little more money. If you bring a reusable shopping bag at home, it is not only strong, but also does not cost money to buy a shopping bag.
If it is convenient, try to go shopping later. Although many supermarkets close at 9 pm, if you shop before closing, you can often buy some special products. These goods are mainly food, such as bread, hamburgers and so on. And fresh vegetables and fruits. This is because these things have strict shelf life, and it is difficult to sell them after one day, so try to discount them. Of course, buying these things must also be rational. Don't buy a pile of hoarding, and finally lose money because you can't throw it away in time.
Pay attention to the activities of supermarkets. Supermarkets often distribute shopping promotion leaflets in the community. These leaflets are quite cheap during the preferential activities. If you happen to have the corresponding purchase demand, you must buy it during the activity, and the same goods cost less. At the same time, supermarkets will often issue some coupons, or they can put them away and make good use of them, and take them out for cash when they can come in handy.
Make a detailed list before you go shopping in the supermarket. Try not to buy what you can, and wait until you need it. Otherwise, you will buy a lot of meaningless things back, which is not only useless, but also takes up space and energy for safekeeping. When shopping, pay more attention to those things that are placed on the humble bottom. Those things are often special or low-priced goods, which may be unsightly in packaging, but they are very practical.
In addition, there will be many supermarkets around a community, and the characteristics of each supermarket are different. In other words, the prices of the same kind of goods in different supermarkets are different. For example, oil and rice in supermarket A are cheap, and meat and toilet paper in supermarket B are cheap. Accumulate as much experience and compare as possible in the process of frequent shopping, so that you can buy what you need at an affordable price in the right supermarket.
Don't throw away the shopping receipt, especially when shopping in concentration. Sometimes, in the event of major events such as store celebrations, these receipts can be exchanged for some gifts when accumulated to a certain amount, which is a windfall. Of course, this receipt is also an important basis for your return.
If shopping is concentrated, you might as well get a supermarket membership card. It may not cost much, or even be open for free, but it can bring you many discounts in your daily shopping.
Most of our daily consumption flows into the supermarket. If we can find some tips to save money in supermarket purchasing, it is undoubtedly an effective means and way to reduce living expenses.
For experienced housewives, it is generally known that bulk food in supermarkets is cheaper than that in bags. Although bulk food is cheap, it is not very healthy. Not only is it easy to get into dust, but the surroundings are also easy to touch and not clean. Therefore, people should pay attention to the following kinds of food when shopping in the supermarket.
I. Cereal bulk food
Bulk grains are easy to breed germs and lose a lot of nutrients. Because grains contain water, relatively humid environment will lead to the breeding of germs. Among them, aflatoxin, a carcinogen, is the most harmful to human body. Chinese medicine reminds that the last thing to buy in bulk is brown rice. Although rich in nutrition, the shelf life is very short, usually only half a year. Especially vitamin A and vitamin C, if they are left in the air for about 3 months, they will be completely oxidized and their health care function will be lost.
Second, bulk edible oil
Most of the bulk edible oil has no packaging label, which is a so-called "three noes" product and has serious health risks. Never buy it. In particular, it is unacceptable to buy a large amount of cooking oil at one time. This is because, first of all, the oil is generally stored in the kitchen, with high temperature and high humidity, which is easy to breed bacteria; Second, the oil in the oil is prone to oxidative rancidity, which will increase the risk of cancer. Therefore, experts suggest that edible oil should be purchased in small packages and eaten within 3 months after opening the lid. At the same time, it should be reminded that. The storage time of edible oil is also related to the type of oil. For example, olive oil can only be stored for 6 months, and peanut oil can only be stored for 3 months after opening.
Three, bulk frozen food
Don't think that frozen food can be preserved for a long time without scruple. Its shelf life is actually only one or two months. It is not easy to judge how long it takes to transport and store a wide variety of frozen foods in the supermarket freezer. So, no matter how busy you are, don't let frozen jiaozi and frozen meat fill the freezer of the refrigerator. It is best to buy and eat frozen food now, which is also a very key point in the four seasons health care.
Four, bulk seasoning products
Whether it is bulk pepper, cumin or bottled Chili sauce, the taste will become weak in about half a year, and the seasoning ability will be weakened, which is easy to breed bacteria and is very harmful to health. Condiments must be bought in small batches, and it is best not to buy them in bulk or in large bottles.
